Abstract
The self-sealing bag comprises a thin, flexible polyethylene bag having a tapered neck. The bag may include indents in the neck to help hold a filling nozzle. A tapered nozzle is inserted into the tapered neck to fill the bag. An alternative tapered nozzle can have two conduits to permit simultaneous filling and air bleeding. As the bag is filled, the sides expand, and the expanded sides exert pressure on the bag sides at the tapered neck to force the bag sides together and thereby seal the bag.
Claims

A self-sealing container comprising a body having a body opening, a tapered neck, and two top sealing flanges, so that when fluid is placed in the bag, the bag expands, exerting sufficient pressure in the tapered neck to close the tapered neck and retain the fluid in the body.
